What pressure does the lateral surface of a long straight solenoid with n turns per unit length experience when a current I exists through it?

Obtain the expression for the mutual inductance of two long coaxial solenoids S_(1) and s_(2) wound one over the other, each of length L and radii r_(1) and r_(2) and n_(1) and n_(2) number of turns per unit length, when a current I is set up in the outer solenoid S_(2) .

The self-inductance of a long straight solenoid is L. Each of the length, the diameter and the number of turns of another solenoid is double that of the first. The self-inductance of the second solenoid is

An electron is moving parallel to a long, straight current-carrying wire. Does it experience any force?

The magnetic field at a distance 1 m from a long straight conductor is 10^(-7)T . What is the current through the conductor?

A long round conductor of cross-sectional area A is made of a material whose resistivity depends only on the distance r from the axis of the conductor as p=alpha/r^2 where a is alpha constant. Find (a) the resistance per unit length of such a conductor, (b) the electric field strength in the conductor due to which a current I flows through it.

A solenoid with 7 turns per unit length is carrying a current of 2.5A . What is the magnetic intensity inside the solenoid ?

A long solenoid carrying a current produces a magnetic field B along its axis. IF the current is doubled and the number of turns per unit length is halved, the new value of he magnetic field is-

The magnetic field B within a solenoid of length L with N turns and carrying a current I is given by

Two solenoids made of insulated conducting wires and of equal lengths are such that one is wound over another. Resistance of each of them is R and number of turns per unit lenghts is n. The solenoids are now connected in parallel and the combination is then connected with a battery of emf E. if current flows through them in the same direction in both cases, determine the magnetic field along the axis of solenoids in each case.
